I have to disagree with both previous posters, I've never met Victoria (and I'm not sure why not because she always looks like a bundle of fun and gets great reviews) but I'd definitely say that she was anything but Goth. She may like a certain style of music but definitely doesn't have the Goth look which I'd assume in a booking is what youd be looking for. If it is the music just ask any girl you fancy to throw some Marilyn Manson or Evanescence on full volume while you do it.
I have met Lydia and I'd describe her as rock chick rather than Goth. She does have an amazing array of tattoos. Maybe I'm wrong but I'm going to guess Lydia wouldnt describe herself as goth either.
I'm not sure she still works but a couple of years ago there was a girl in Gateshead called Mistress Bizzare who I would say was 110℅ Goth.
